Abstract: ABSTRACT OF THE DISCLOSURE       In order to improve the efficiency and reliability of the cutter units employed in large scale ice disaggregation sys-tems, a cutter configuration is employed characterized by an out-wardly extending arm which sweeps rearwardly from the direction of travel to provide clearance for ice chunks and then sharpwardly forwardly to terminate in an ice-engaging portion.  The ice-engag-ing portion includes a relatively long and narrow central "pick" portion for breaking very cold ice, chisel-like cutting edges directed to each side of the base of the "pick" portion to frac-ture cold ice as well as warm ice, and an inverted skate portion which cleaves the ice and promotes passage of the ice chunks around the tooth structure to facilitate clearing.

Abstract: Apparatus For Suspending A Trunnion Axle Assembly From A Vehicle Abstract Trunnion mounted axle assemblies are used on farm tractors, fork lift trucks, golf carts, and earth moving vehicles such as front end loaders.  Normally, such axles are mounted by pillow blocks to the vehicle frame and rotation of the axle is resisted by resilient elastomeric bushings which act as torsion springs. These bushings do not provide as long a service life as desired and must frequently be replaced.  The present invention overcomes this problem by providing a resisting bar rigidly attached to the end of each trunnion and a resisting cap containing a resiliently deformable member.  The bar is received in a slot.  The assembly can be adjusted as necessary to compensate for wear.

Abstract: ABSTRACT:         A solenoid drive circuit for an impact printer comprises a capacitor which is connected in parallel with the series arrangement of a first diode, the solenoid coil, and the base-emitter path of a transistor.  A second diode is connected in parallel with the coil and the tran-sistor. The capacitor is charged from a d.c. supply, which includes a switching regulator, via diode.  When the transistor is switched ON by a printer signal applied to  a terminal the capacitor is discharged resonantly into the coil.  The first diode prevents the negative half cycle of the resonant frequency and current in the coil circulates in the loop formed by the coil the transistor and the second diode when the transistor is switched OFF the current flowing in the coil is discharged via a further diode into the reservoir capacitors of the d.c. power supply to increase the efficiency of the drive circuit.  The print signal is also fed to an inhibit input of the pulse width modulator to switch OFF a further transistor in the switch-ing regulator during the print operation.

Abstract: ABSTRACT          The invention relates to an appliance for heating an electro-conductive material, preferably one which hardens as a result of this heating process, this material being in the form of a continuous strand which is guided inside a channel.  In this appliance, a high-frequency generator feeds a capacitor assembly which includes two capacitor-plates arranged on two oppositely-located sides of the channel formed by four synchronously driven insulating belts.  These capacitor-plates are staggered by at least their length and are connected to a non-earthed terminal of the high-freqency generator.  The capacitor assembly includes two further capacitor-plates are arranged on each of the two sides, adjacent to the two capacitor-plates, these further capacitor-plates being connected to the earthed terminal of the high-frequency generator and extending along the channel for a distance such that the strand outside the heating zone is no longer at a potential higher than ground.  The appliance can be used, in particular, in a belt-type continuous--moulding unit for the manufacture of blanks for building materials, starting from a raw mixture having a high dielectric coefficient.

Abstract: Abstract of the Disclosure Method and apparatus for transfer of packet-type information from the memory of one node in a computer network to the memory of another node in the network.          The invention is of particular utility in transfers over serial buses.  Packets are sent from a named memory buffer at a first node to a named memory buffer at a second node allowing random access by the first node to the memory of the second node without either node having to have knowledge of the memory structure of the other, the source and destination buffer names are contained right in the transmitted packet.  The first node can both write to and read from the second node.  An opcode sent in each packet signifies whether a read or write operation is to be performed. For reading from the second node, the opcode actually causes the second node to write back to the first node; in this situation, the second node, upon detecting the appropriate opcode, places the remainder of the received packet on a command queue, to be executed with the commands locally generated at the second node, without need for host interruption.

Abstract: ABSTRACT OF THE DISCLOSURE         A system for high speed acquisition and storage of data from transient electrical signal waveforms sampled in time at a multiplicity of points, and where it is desired to collect and store data in real time in a mass storage unit, but where the data rate is in excess of the apparent rate at which data can be transferred to mass storage.  The overall system employs two levels of data reduction, the first being digital integration (summation) and the second being data processing.  In the digital summation section memory read and write cycles overlap for higher speed.  In one embodiment, a charge-coupled device is employed as an input element to reduce the data rate prior to subsequent digital processing.  The system is capable of recording all the intensities of all transients continously without loss of data significance.
